Japanese Garden Back Portrait with Knotted Chiffon Dress

Output Contract: Generate a vertical 3:4 realistic fashion portrait of an adult woman viewed from behind, standing beside a pond in a lush Japanese garden. The figure must occupy a large portion of the screen, captured from top of head to mid-thigh. No text, logos, or watermarks.

Subject Lock: Adult woman with natural, calm atmosphere. Hair: shiny dark brown short layered bob, chin-to-neck length, ends flowing outward, thin bangs, delicate strands around face. Eye makeup: pale pink-brown, thin natural lashes, soft brows. Lips: subtle rose-beige. She faces diagonally downward, eyes cast toward bottom right, thoughtful expression, relaxed mouth. She twists her upper body slightly to her right, showing a refined profile over her right shoulder.

Theme: {argument name="theme" default="Knot of White Fabric"}.
Clothing: {argument name="clothing" default="A long dress layered with thin, soft ivory-white chiffon."} Dress has wide-open back. Opaque lining near skin tone covers necessary parts while subtly suggesting body contours. Left and right fabric tie into a thick knot at center of back slightly above waist, long ends flowing downward. Right arm hangs along body, right hand lightly pinching hem. Left arm tucked into fabric at side. Weight on left leg, slight shoulder height difference.

Composition & Camera: Camera behind and slightly to right of subject, approximately shoulder height. Vertical 3:4 aspect ratio. Face in upper center slightly right; back and knot in center. Left side: wide bright margin of water surface. Right side: depth from diagonal lines of veranda and stone arrangement. Use 85mm equivalent medium telephoto lens with shallow depth of field. Focus on face, hair outline, shoulders, and knot; pond and building smoothly blurred.

Background & Setting: Peaceful pond with tree reflections on left side. Background: {argument name="background setting" default="A vertical 3:4 realistic fashion portrait capturing an adult woman from behind, standing by a pond in a lush Japanese garden."} On the right: natural mossy stones and the veranda of an old wooden building. Shoji doors, wooden pillars, and deep green trees compose a quiet Japanese garden with minimal signs of daily life.

Lighting & Palette: Warm morning light from upper left, gently highlighting hair outline, neck, shoulders, and upper back. Add thin blue-green reflection from pond on shadow side. Dappled sunlight spots on rocks and veranda. Color palette: white and pale skin tones, deep green foliage, dark brown wood, blue-green water. Achieve magazine photo finish with soft contrast, natural three-dimensionality, and stillness.

Texture & Style: Maintain fine skin texture, avoid excessive retouching. Precisely depict chiffon's transmitted light, fabric layering shades, fine wrinkles, knot thickness, and natural shine of individual hair strands. Do not make skin appear plastic or over-smooth. Overall style: elegant Japanese fashion photography with a calm, refined tone.

Exclusions: Person looking underage, excessive exposure, explicit nudity (dress must be modest but back is bare), unnatural face or gaze, extra or missing fingers, fused limbs, broken joints, poor fabric-to-body contact (knot must appear tied securely), unnatural knot (floating or loose), broken shoulder alignment, wrong perspective, shadows inconsistent with light source, excessive skin retouching, plastic-like skin, gibberish text, logos, watermarks.
